Happy New Year @Greencedar
You're also doing an amazing job with your Malawi and Zamaldelica grow reaching mid flowering! 
Pure Hazes or pure Thais need to finish under 11/13 or 10/14 light cycles; otherwise, they remain stuck in perpetual early flowering stretch under a constant 12/12. That’s not the case for Malawi, which is a much more tamed line, especially the feminized version. Shorter flowering Malawi expressions perform great indors under 12/12, while the taller, longer flowering phenotypes benefit from switching to 11/13 for the final two/thirds of the flowering period.

I have a question regarding hours of light. I’ve flowered hazes/thais on shorter light regiments (11/13 or 10/14). Would using these light regiments with more tame sativas like the New Killer Malawi pheno result in a less potent final product or is it only yield that suffers a bit? I’ve heard some stuff about plants expressing different traits with different light schedules (DJ short talks about this) but I don’t have the experience to know how true this is. This might be a question for Dubi but it would be great to hear from anyone else that has played around with this and ace genetics.
